I assume you mean, that an angle and two sides are known.
A formula that can be used for irregular triangles is the cosine rule.

'b' and 'c' must be sides that are beside the angle 'A' (angle opposite 'a').

If there are 4 marbles left over each time, then we can forget about them for now.
So the question is, what is the smallest number than can be divided into 6,7 and 8?
the numbers have only one non-1 divisor in common: both 6 and 8 are divisible by 3.
so for our purposes we can "delete" one 2 and ask:
what is the smallest number than can be divided into 3,7 and 8 ?
There are no more divisors in common, so we just have to multiply them: 3*7*8=21*8=168
and the 4 marbles "extra"? We add them to this sum.
the the smallest possible number in the box is 168+4=172.
The word 'more' means to add, so
-2+6=4
we need to find out the square root of 4
√4=2
ANSWER=2
